Abstract: Nutritious rice bran powder was based on the ripening rice bran flour as the main raw material. It was based on single factor and orthogonal investigations to determine the optimal formula and the result of sensory evaluation test.Results: Ultrastructural defatted rice bran powder optimal formula ( with main raw material powder10 g as unit) : defatted rice bran powder 20 g, whole milk powder 55 g, sugar powder 25 g, xanthan gum 0.22 g, CMC0.08 g, microcrystalline cellulose 0.23 g and the score was 87.
